-- == Description
--
-- When using a framebuffer with mixed samples, a per-fragment coverage
-- reduction operation is performed which generates color sample coverage
-- from the pixel coverage. This extension defines the following modes to
-- control how this reduction is performed.
--
-- -   Merge: When there are more samples in the pixel coverage than color
--     samples, there is an implementation-dependent association of each
--     pixel coverage sample to a color sample. In the merge mode, the
--     color sample coverage is computed such that only if any associated
--     sample in the pixel coverage is covered, the color sample is
--     covered. This is the default mode.
--
-- -   Truncate: When there are more raster samples (N) than color
--     samples(M), there is one to one association of the first M raster
--     samples to the M color samples; other raster samples are ignored.
--
-- When the number of raster samples is equal to the color samples, there
-- is a one to one mapping between them in either of the above modes.
--
-- The new command
-- 'getPhysicalDeviceSupportedFramebufferMixedSamplesCombinationsNV' can be
-- used to query the various raster, color, depth\/stencil sample count and
-- reduction mode combinations that are supported by the implementation.
-- This extension would allow an implementation to support the behavior of
-- both @VK_NV_framebuffer_mixed_samples@ and
-- @VK_AMD_mixed_attachment_samples@ extensions simultaneously.
